Thanks for your reply, it's set my mind at rest. No didn't mention it, he was on his own the night we got them, having to catch them and do the paperwork plus trying to get everyone to take less than they originally asked for as he was short of hens, so he was a bit rushed and flustered, he was just going in and grabbing them, sticking them in their boxes and moving on to the next lot. Also to be honest never having had chickens before i wouldn't have known, it's only since getting to know them that i can see its been done, taking kitten to vets on Monday to get neutered so will inquire while there if they have any knowledge of poultry.
